Product Description:

Hawks Motorsports offers our clients this 1964-1966 Mopar A-Body A41 4L60E 4-Speed Automatic Conversion Kit | 650 lb-ft Capacity | A41-MOPAR-ABODY-6466. This A41 automatic conversion kit upgrades classic Mopar A-Body vehicles with modern overdrive technology, improved drivability, and electronically controlled transmission performance.

Vehicle Configuration Required

Transmission conversion kits are vehicle specific. Complete the Hawks Motorsports Transmission Conversion Request Form before ordering so our team can verify compatibility and confirm the correct components for your application.

Installation Notice: This is a basic builder's kit. Cutting and/or fabrication may be required during installation depending on vehicle configuration. Verify drivetrain specifications before ordering.

Designed for 1964-1966 Mopar A-Body applications including Dodge Dart, Plymouth Valiant, and Plymouth Barracuda, this A41 4L60E automatic conversion kit provides a modern four-speed overdrive solution for enthusiasts looking to improve cruising comfort, acceleration, and reliability.

The A41 utilizes a GM 4L60E / 4L65E aftermarket replacement transmission platform with electronically controlled shifting and lockup converter technology. Gear ratios of 3.06, 1.63, 1.00, and 0.70 provide improved acceleration and reduced engine RPM during highway driving compared to many original Mopar automatic transmissions.

Available in three performance stages, the A41 can be configured for different driving applications. Stage 1 supports up to 450 lb-ft of torque, Stage 2 supports up to 550 lb-ft of torque, and Stage 3 supports up to 650 lb-ft of torque for higher-performance builds.

The A41 4L60E is an excellent replacement option for aging transmissions such as the Mopar 904, 727, 518, Powerglide, TH350, TH400, 200R4, and 700R4. Modern overdrive technology provides smoother operation, improved acceleration, and up to a 30% reduction in cruising RPM.
